JOURNAL-BOX.

SPECIFICATION forming part of Letters Patent No. 351,015, dated October 19, 1886.

Application filed June 23, 1886.

To all whom, it may concern.-

Be it known that I, JAMES B. ALLFREE, a citizen of the United States, residing at Gumberland, in the county of Alleghany and State of Maryland, have invented new and useful Improvements in Eccentrics and J ournal- Boxes, of which the following is a specification.

This invention relates to certain new and to useful improvements in eccentric journals and journal-boxes; and it consists, substantially, in such features of construction and combinations of parts as will hereinafter be distinctly described, and pointed out in the claims.

The objects of the invention are, first, to provide ajournal box or bearing of such construction as that a self and continuous supply of oil or lubricant will be had for the eccentric journal during its rotation or movement in the box, thus promoting the longevity of wear of the parts, and obviating the necessity of frequent replenishing of lubricant.

Second, the invention has for its object to provide simple and effective means by which 2 the eccentric journal is made variable with re spect to the driving-shaft for increasing or diminishing the stroke of the rod or other device designed to be operated, and by which the said eccentric journal may be adjusted 3o horizontally to set or bring it to the proper position.

Finally, the invention has for its object to simplify the construction of parts, and to economize in cost over many former inven- 3 5 tions of an analogous character, all as will appear from the description hereinafter following.

Referring to theaccompanying sheet of drawings, Figure 1 represents an end view of an 0 eccentric journal and journal-box embodying the principles of my invention. Fig. 2 represents a vertical sectional view of the journal-box on the line 00 m of Fig. 1, by which the interior construction of the same is more clearly 5 understood; and Fig. 3 represents a longitudinal sectional view to indicate more clearly the manner of adjustment of the eccentric journal horizontally, and ofvarying its eccentricity with respect to the driving-shaft.

In carrying my invention into effect I pr0- Serial No. 205,906. (No model.)

vide a journal-box, A, preferably divided or split at the top, as at a, and held togetherby an adjusting-screw, b, by which a regulation of the ease of movement of the eccentric j ournal is had and the wear of the parts compen- 5 5 sated or taken up. This box is provided with an annular flange, c, which surrounds the inner end of the opening in the box, as shown, and is for the purpose of preventing the journal-box from slipping away from the eccentric journal, and also of preventing the escape of lubricant from that end of the box. At the opposite end of the box, on the interior thereof, an annular groove or chamber, (1, is formed, that is designed to catch or receive the oil thrown off from the outer end of the eccentricjournal centrifugally during the rotation thereof through its connection with the driving-shaft, while in the bottom of said box a longitudinal groove or chamber, 6, is formed, the same being designed as the reservoir for the oil, and as a conduit to convey the oil back to the body of the eccentricjournal B. The eccentric journal is constructed of such length as to have its outer end or edge extend past the inner wall, and about opposite the middle of the annular groove (Z.

By the construction thus far explained itwill be seen that by placing asuitable quantity of oil or other proper lubricant in the longitudinal 8o groove 6 the rotation of the eccentric journal within the box will cause it to gradually spread around and be carried out centrifugally at the end,where itis caught orreceived by the annular groove d, from whence it gravitates or flows back into the longitudinal groove or reservoir 6, and thence back to the eccentric journal, thus obtaining a self and continuous oiling of the parts. The eccentric journal Bis formed or provided with a stem,f, by which it is adjustc ably connected to the driving-shaft O by means of a set-screw, g. \Vhen only the degree of thrust is desired as is permitted by the difference between the geometric centers of the eccentric proper and its stem f, I provide the 5 end of the drive-shaft O with a central bore that is, with a bore whose center is coincident with the center of the eccentric-and thus will this particular degree of thrust or eccentricity be had 5 but when a variable degree of ecceu- 10o then securing it by the set screw 9 at such point horizontally as to permit proper action,

and thus will it be seen that a most thorough adjustment or regulation is effected. I

It is obvious that instead of forming the eccentric journal and its stern integral or in one piece, the same may be formed separately and then united. by any proper method.

On one side of the box A an extension, 'h,

is formed, by which suitable attachment thereof may be made by a screw and nut to the rod or other device to be operated. h

The invention was devised more particularly for use in roller flour-mills, and for the purpose of operating the shaking or vibratf ing shoes of the hoppers through which the' coarse cereal or grain is fed to the rolls, itbeing frequently desirable to vary or alter the" degree, of movement of'suc'h shoes to regulate the delivery of the material.

the operation of my invention will be thoroughly understood, and I would state that while I'have he rein shown and described certain constructions of parts the 'same'can be very materially changed without departing from the spirit of the invention. I
